First 5 patches convert us to %r0-31.
Next 12 convert make using R0-31 required in macros.
Last 2 convert instructions where ra = r0 we use 0 rather than the
register value (as suggested by Andreas).
Version 4 add:
Fixes for bpf_jit code
Version 3 adds:
Fixes for chroma (moved some defines ppc_asm.h -> ppc-opcode.h)
Fixed comment in sldi patch to reflect new change (thanks Segher)
Version 2 adds:
ra = 0 idea (as Andreas suggested)
Fixes for 32bit KVM (added ppc44x_defconfig to my testing)
Based on mpe's next tree which has Antons power7 copy patches which
